What is the minimal amount of fat you should be taking in to have your body function as it should be?

Generally, fat is seen as a percentage of your overall intake, so the more food a person consumes, the more fat they will consume to keep the ratios in balance.

Though, for certain people that have particular medical conditions, fat intakes at lower levels are more desirable. 15% to 20% is a decent range for fat intake, though 10% is also adhered to by some. It has to be remembered though that fat intake is also correlated to specific sports as well and some sportsmen/women consume lower levels of fat depending on what sport they are doing.

20% seems to be an average percentage of total calories that weight lifters use, though, it can also be higher or lower than that.
